To all whom #may concern: A i

Be it known that LJESSE G. VINCENT, aci-tizen. of the United` States, residing ati Detroit, Wayne. county, State of Michigan, have invented certain-new arid useful Im. provements in Motor-Vehicles, of which the following is a-specifioation.V

Thisinvention relates to 'motorl vehicles'I and particularly -to .the transmission mechanism and its supporting casings;

One of the provision fofasimple yand reliable shift-inguy me'chanismand also'an improved -formof drive .-for. anaauxiliary pump. t'

VAnother object of the invention: is the provision yof a.nove1 casing and support' vfor the clutch and gearingand their associated parts. i

` Other objects-andthe features of'novelty will :be apparent from theV following descrip tion, .taken iniconnectionfwith the accompanying drawings, in which: Fi ure -1 is a Elongitudinal section through the clutch and transmission gearingrcasings ofa motorrvehicle, 'embodying my; inven' tion.; i

Above will pass the shaft 29 the casing 13 is provided with a relatively large opening 29 throughwhich the shaft 29 may be removed when detached from the parts 31 and 32 and the trunnions 26. The opening 29 is normally closed by a cover plate 29". A passage-35 in the stub shaft 31 communicates with a passage 36 in the wall of the casing and lubricant may be supplied to the latter passage in an suitable manner -as by means of the cup 37. From Fig. 3 it willbe evident that the lubricant from the cup 37 through the passages 36 and 35 and thearms 30 to the passages`27 in the trunnions and thence into the rollerbearing 25.

Conduits 38 for the motor wiring or forV any other desirabley purpose extend transversely across the clutch casingand are secured in the yside walls thereof, as indicated at 39 and 40'in Fig. 3.

`The rearward end of the shaft 16 is enlar ed within the casing 15- and' provided wit gear teeth 41 on the exterior of the enlargement. The enlarged end is cupped out to receive a bearing end 43of the gear shaft 44, the rearward end of this shaft beingsupported in a bearing 45 in the` rear wall of the transmission gearingcasing. On thezexterior of the casing the shaft 44 is provided with a flange 46 to -which auniversal joint or other suitable form of connection may. be attached. The yshaft 44 is preferably provided witha plu- .I'ality of keys 47 andhas slidably arranged thereon the gears 48 and 49. The gear 48 has internal teeth 50 adapted to mesh with the teeth 41 to form a direct connection betweenthe shafts 16 and 44..l A counter-shaft 51 is mounted in the bearings 52 and 53 and has keyed thereon the gear 54 'which con-v stantly meshes with'the teeth-41. The shaft 51 also has keyed thereon the gearsv 55, 56 and 57, the gear 48 being adapted to be moved into meshwith the gear 5.5 and the gear -49 being adapted to be moved into mesh with the gear 56. An intermediate gear 58 yis mounted on the short shaft 59 (see Fig. 4)

and'permanently meshes with the gear 57. The gear 49 is adapted to be moved into mesh with the gear 58, as shownv in Fig. 2, so

that-the shaft 44 may have its direction of rotation reversed from that of the shaft 16.-

The casing 15 is provided with an opening 60in the side thereoffthrough which the rgear 58 slightly projects and a pump 61 is secured on the exterior of the casing 15V and operated by a shiftable gear 62', which is arranged to be driven fromthe gear 58. The gear 62k is i moved into and out of mesh with the gear v58 by any suitable mechanism such as the arm 63,*which is mounted on the vertical shaft 64. The haft 64 projects through the casing 65 of the'pump'and carries exteriorly of the4 casing an arm 66 with which a spring 67 is connected.v From Fig.'4 it willvbe seenthat movement andy shift the arranged to coperate -able plugs 72 rwhich 42which supports the f side Walls of the to be actuated thereby.

by swinging the arm 66 to carry the axis of the spring over the axis of the shaft 64, the spring will then automatically continue the with the gear 58. When t e arm 66 is in the position shown in Fig. 4 it is automatically held by the spring 67.

In order to shift the gears 48 and 49 into and out of mesh with the gears which are therewith, two shiftable elements 68 and 69, preferably in the form of rods arranged tomove parallel with' the axis of the shaft 44, are provided. These rods have their ends mounted in bearings in the front and rear walls of the gear casing, two of thes'e bearings being indicated at 70 in Fig. 4. The ends of the rods 68 and 69 are inclosed in tubes 71 and these tubes have glear 62 into mesh arranged in the outer ends thereof adj'ustl are adapted to be enthe ends of the rods 68 and 69 to eased by of the rods. Any suitlimit the movement able means may be provided for securing the plugs-.72 in their proper position and for this purpose locking wires 73 are indicated on the drawings.

The rod 68 has secured-thereon an arm l74 having a yoke 75 at its end which engages the grooved hub 76 of the gear 48.l The rod 69 has secured thereon anarm 77' having a yoke 78 at its' end which engages the grooved hub 79 of the gear 49. Thegears 48 and 49 are thus operatively connecte-d with the rods v 68 and 69, respectively, movements of the'latter.

Ashaft 80'is arranged in the upper part of the casing-15 and mounted in suitable and partake of the '-I bearings 8l and 82, whichare secured to the l casing. A brake pedal 83 and a clutch edal 84 are mounted on the tubular-extension 85 of the bearing 82. The link 34 is connected .with the pedal 84 so as The shaft 8O is arrangedto be moved axially in the bearings 81 and 82 and carries on one 'end a washer or plate-87 |which is adapted to engage an abutment 88 to limit the axial movement ofthe shaft in one. direction. An

arm 89 is secured on the shaft 80 and has its lower end arranged to coperate with the rods 68 and 69, these rods being provided with transversegrooves 90 and 91, respectivelyf,'into which the end y92A of the arm 89 is adapted to project. When the rods 68 and '69 are in their neutral positions the grooves 90 and are' in alinement so that the end 92 ofthe arm 89 may be shifted from the groove 90 to the groove 91 or vice versa. From Fig. 2 it will be' evident that by rock- -ingthe shaft 8O the rod 68 may be shifted,

The bolt 93 carries a roller 103 which cooperates with the roller 99 to cause the Ibolt to be moved With the axial movements of the shaft 80. In the Adrawings the parts are shown in the neutral position and from Fig. 4 it will be seen that the lower end of 'the extension 100 is of triangular cross section and provided with a recess 104, which receives the roller 99 to hold the parts in their neutral positions. `W'hen the shaft 80 is rocked, the roller 99 leaves the recess 104 'and coperates. with the edges 105 and 106 of the extension 100 to assist the operator in rocking the shaft and thereby sliding the gears into meshing position and to yieldingly hold them in such position. AFrom Fig. Q'it will be' evident that when thebolt 93 is shifted in- Wardly from the osition shown, the groove 94 in the. holt will be moved into alinement with the rodV 69 and the bolt will secure the rod 68 against movement. At the same time the end 92 ofthe arm 89 is shifted from the groove to the groove 91, so that when the 65 shaft 80 is rocked the ro-d 69 will be actuneutral', posilsigus. and.i
